    "abstract": "We consider a slab of nuclear matter and investigate the collective\nexcitations, which develop in the response function of the system. We introduce\na finite-range realistic interaction among the nucleons, which reproduces the\nfull G-matrix by a linear combination of gaussian potentials in the various\nspin-isospin channels. We then analyze the collective modes of the slab in the\nS=T=1 channel: for moderate momenta hard and soft zero-sound modes are found,\nwhich exhaust most of the excitation strength. At variance with the results\nobtained with a zero range force, new \"massive\" excitations are found for the\nvector-isovector channel .",
